Whilst I agree with your point it is the large gold firms who are lowering the prices incessantly & for no good reason other than greed, not enterprise. They simply want to ship their stock before their account gets banned and that is a fact.
EDIT: Those who call this smart economics? You're wrong. "Smart Economics" Would be buying a small amount of gold and selling it for a higher price and getting a better profit per unit. Not buy bulk & risk big for worse long term gains. Stay smart people. Don't buy what you know you won't be able to sell and don't have eyes bigger than your belly ^_^.
Rs07 gold is not a good that's price deteriorates or improves in Individual demand due to falling or increasing PPU (which is what individual demand would normally constitute), because people buy it when they NEED it, for the average price that is on the market. This has been seen as due to the imminent release of RuneScape 3, old school players have been turning their attention towards the EoC gold market and stocking up for a week or two of playing that instead, therefore eliminating their need for 07 gold, hence what I was saying in the OP. There is not enough demand, but this is not a reason to lower prices until you reach rock bottom. I hope you can see what i'm saying and not use "basic economic" terminology with me, I do know what you're talking about, but it does not apply in this instance.
